ABSTRACT:
A children's computer keyboard includes enlarged keys that are color-coded according to their functions, and a four directional arrow-key pad of unique configuration. Characters on the keys of the children's computer keyboard are also enlarged for improved visibility. The enlarged keys provide wider top surface dimension between keys which provides each key with a larger error free area than a standard sized keyboard thus more tolerant for human error. A keyboard connector/extension cord with separable parts is provided for easy keyboard changing.
